COVID-19 Data analytics Dashboard
This dashboard visualizes COVID-19 vaccination doses administered across the United States. A dropdown menu selects a state, displaying its daily vaccination bar chart. A map shows the latest daily doses for each state, with circles sized proportionally. Brushing the bottom bar chart updates the map to display data for the date at the end of the selected range. The visualization uses React with d3.forceSimulation for non-overlapping circle placement and d3.geoPath for map rendering, sourcing data from US Vaccination Data by State/Territory.
